Four TESS sectors leave two period aliases of TOI-7583.01 unresolved under a Gaussian dip model

We tested whether four public TESS QLP light curves distinguish the TOI-7583.01 period from the period of a known nearby Gaia binary. A Gaussian dip model gives separate solutions at 0.718031322 and 0.717328877 days. The Gaia-like solution has a lower weighted residual score by 8.02, but a conditional cycle-bootstrap interval for the difference is -26.22 to 10.03. The catalog periods have a beat time of 730.75 days, close to the gaps between TESS visits. Aperture and raw-flux checks retain both solutions. Sparse independent ZTF data do not confirm either signal. Thus, a large quoted period discrepancy alone is insufficient to reject the nearby binary under this sampling. We do not locate the source or validate a planet. The model, correlated errors, and retrospective selection limit the result. We preserve raw inputs, source hashes, code, fitted models, bootstrap draws, and offline instructions.
